Abstract We probe the stellar mass growth in a sample of 568 Sunyaev-Zel’dovich (SZ) selected galaxy clusters with masses greater than 2.9 × 1014M⊙ and redshifts in the range 0.2 < z < 0.8, drawn from the fifth data release of the Atacama Cosmology Telescope (ACT DR5). By utilising deep photometry from the tenth data release of the Dark Energy Camera Legacy Survey (DECaLS DR10), we construct redshift- and cluster mass-binned composite cluster stellar mass functions (SMFs), down to
